Abstract
Apparatuses and methods for transmitting and receiving signals in a mobile communication system are provided. A method for transmitting a signal by an evolved Node B (eNB) in a mobile communication system includes transmitting a same control channel signal to each of a plurality of Radio Units (RUs), and transmitting a different data channel signal to each of the plurality of RUs. A data channel signal transmitted to each of the plurality of RUs may be determined taking into account at least one of a location of a User Equipment (UE) that will receive the data channel signal, and load balancing.

A method for transmitting a signal by a base station in a wireless communication system, the method comprising:
- determining a plurality of user equipments (UEs) with a maximum scheduling metric based on channel quality information;
- generating a common signal for the plurality of UEs;
- generating a radio unit (RU) specific data signal for each of RUs;
- multiplexing the common signal and the RU specific data signal;
- and
- transmitting, to each of the RUs, the multiplexed signal on a channel through a common public radio interface (CPRI) based on a wired medium;
- wherein a cell is identified by the plurality of UEs based on the common signal,
- wherein the cell includes a plurality of sub-cells and each sub-cell is identified by at least one UE which is located in the each sub-cell, based on the RU specific data signal.
A base station in a wireless communication system, the base station comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller configured to:
- determine a plurality of user equipments (UEs) with a maximum scheduling metric based on channel quality information,
